Additional information
Predicted data of target chemical and supporting weight of evidence studies for it's structurally similar read across chemicals has been reviewed to determine the effect of the test chemical on aquatic fishes. The studies are as mentioned below:
First study includes the toxicity of the test chemical to aquatic fishes was predicted using EPI Suite ECOSAR version 1.11. On the basis of effect of test chemical observed in a static syst tem on the mortality of the test organism during the 96 hr exposure duration, the median lethal concentration (LC50) for the test chemical was estimated to be >100 mg/l (1790000 mg/l). Thus, based on the LC50 value, test chemical can be considered as non-toxic to aquatic fishes and hence, considered to be 'not classified' as per the CLP classification criteria.
Second study includes an acute toxicity to fish study was carried out for time period of 96 hrs by following the method of EPA-660/3-75-009 (USEPA 1975). Study was performed under statc condition. Juvenile Lepomis macrochirus which was obtained from Lesser Ketones Manufacturing Association Leesburg, VA of length of of 3.4 cm (range 2.8-4.2 cm) was used as test organism which were acclimated to laboratory conditions a minimum of two weeks before testing of loading rate of 10 fish per exposure vessel total of 80 fish were used. Reconstituted soft-water prepared from glass-distilled water was used as dilution water. Test substance was added directly to exposure vessels and 4.2 mL of methanol added to controls because methanol is released on hydrolysis of test substance. Test solutions for range-finding study were prepared 30 minutes prior to addition of fish.Test was carried out at temperature 22°C of pH 7.2 to 7.6. pH at initiation (t = 0 h) mean 7.2 (range 7.2-7.3) 48 h observation mean 8.5 (range 7.4-9.6). Dissolved oxygen initiation (t = 0 h) mean 13.4 mg/L (range 13.0-13.5 mg/L) termination (t = 96 h) mean 8.4 mg/L (range 8.0-8.5 mg/L). Hardness and alkalinity was 40 to 48 mg CaCO3/L and 3 to 35 mg CaCO3/L respectively. Nominal test concentrations used were 0, 10, 100, 180, 320, 560, 1000 mg/L. Duplicate controls and single exposure concentrations were used. Polyethylene-lined vessels containing 10 L of dilution water. vessels were aerated before study initiation but not during study. Time of test solution preparation and time of fish addition were not recorded for the definitive study. Based on effect of mortality of test fishes NOEC, LOEC, LC10 and LC50 values were determined to be 100, 180 127 (65-161; 95% CI) and 200 (157-258; 95% CI) mg/l respectively. Thus, based on LC50 value test chemical was considered as non-toxic to test fishes and hence considered to be not-classified as per CLP classificaton criteria.
Third study includes an acute toxicity to fish study was carried out for time period of 96 hrs by following the OECD Guide-line 203 "Fish, Acute Toxicity Test",DIN 38412 Part 1, EG Guideline 92/69 C.1. Study was performed under semistatic condition. Brachydanio rerio was used as test organism. Test was carried out at temperature 20 to 21°C. The pH values ranged from 7.8 to 8.4 units in the controls and 8.2 to 9.3 units in the test chambers. The DO values ranged from 8.0 to 8.9 mg/L in the controls and 7.8 to 9.0 mg/L in the test chambers. water hardness and TOC was determined to be 18 mg/L as CaCO3 and 6 mg/L respectively.Verification was done analytically using TOC-500 Infrared Analyzer. The tested substance was added to tap water to provide a concentration of 1g/l and stirred for 18 hours. The solution was filtered and the TOC content determined. The test began immediately after preparation of the test solution. The nominal test material concentration was 1000 mg/l. Measured concentrations were 880 mg/l at 0 hours; 922/947 mg/l at 24 hours; 885 mg/l at 72 hours average value of 943 mg/l (water filtered initial solution). 0% mortality in control was observed. Based on effect of mortality, LC0 value was determined to be >= 934mg/l. Based on LC0, LC50 value was considered as > 934 mg/l and hence, test chemical was considered as non-toxic to aquatic fishes and considered to be not-classified a sper CLP classification criteria.
Based on effect of test chemical on the mortality of the test organism aquatic fishes the 96 hrs LC50 value was estimated to be >100 mg/l (i.e 1790000 mg/l).
Based on above information test chemical was considered as non-toxic to test fishes and considered to be not-classified a sper CLP classification criteria.
